Quazar Graphic OLED - Retro Programming in C and Z80 Assembly

#rc2014 #programming #z80 One of the main limits with most Z80 based computers is their lack of any video output. Most video output comes in the form of ASCII text sent to a serial console. This is fine if you like text based software or are running an operating system like CP/M. It's a bit limiting if you want to do more graphical things.

I found the Quazar Graphic OLED Display, a plug in board for the RC2014 Z80 computer with a small 128x32 pixel OLED display on it. By using a fairly straight forward set of z80 assembly routines it's possible to send image data to the screen.

In this video I go through the code and how the screen works. I use a mixture of Z80 assembly and C code with the Z88DK z80 compiler.
